Help!!!

Okay so I am 36weeks and 4days and my SO has just told me that I am not who he fell in love with, and I told him that it is just because I am pregnant and all the hormones and having a baby does change you, and it's making me worried, I need advice on how to be more nice to him and more loving?? Because I used to be so loving toward him and all over him and ever since I got pregnant just like being around or looking at him just irritates me, and I don't want it to be like that anymore! Does ANYONE have ANY ADVICE?! Please please share!
